We tend to think that vegetables are one of the healthiest foods around. But there is one group of plant foods in particular that has 10 to 20 times the minerals and vitamins of “land” vegetables—and that’s sea vegetables, also known as seaweed or sea greens. Often used in Japanese cooking, these vibrantly colored multi-textured foods can help detoxify the body…may have anticancer benefits…and can stimulate thyroid function (in people with low thyroid). To find out more about bringing delicious sea vegetables, such as arame, nori and dulse, to your table, our editors spoke to Jill Gusman, who teaches at the Natural Gourmet Institute in New York City and is the author of Vegetables from the Sea: Everyday Cooking with Sea Greens (William Morrow). Here’s what she recommends…

Sea vegetables are “sea-like” in flavor—and range from very mild to very salty. They are mainly sold prepackaged in dry form in sheets, whole leaves or powders at health-food stores and in the natural-foods sections of many supermarkets. They also are sold online from companies such as Maine Coast Sea Vegetables (207-565-2907, www.SeaVeg.com) and Mendocino Sea Vegetable Company (707-895-2996, www.Seaweed.net). Recipes are available on both sites. More ways to use them…

Snacks. The milder varieties of sea vegetables—such as nori and dulse—make a good crispy snack right out of the package.

Added ingredient. Dried sea vegetables can be hydrated—and then added to salads, soups, stews, omelets and vegetable side dishes (they are delicious sautéed with carrots, mushrooms or squash). Soak dried sea vegetables in water for about five to 10 minutes or until tender. Drain.

Powdered seasoning. Dulse, for example, is available as a powdered seasoning. Use it to flavor vegetable dishes, pasta, soups or even popcorn. Seaweed seasonings provide a subtle sea-like salt flavor that is different from that of table salt.
